You're welcome! I try to keep people informed when new titles hit the shelves.Many people have played the ROM already, and I have not yet found if any improvement was made.At least this is an official release.

I never played it, but I like to support this kind of physical releases, I like RPGs and I've seen some good reviews about the game, so I ordered it.

I don't know if they changed/improved anything. I suppose they can use the unofficial English translation without asking permission to who made it. Does this game has any stolen sounds/sprites from other games?

Piko seems legit. They seem to go out of their way to get permissions and copyrights. From what I understand, they fix bugs and improve where needed. I doubt that they will use someone else's translation without permission, as they are currently looking for translaters on their twitter.
